Gilles Fauconnier and Mark Turner explore another conceptual aspect of metonymy. In their paper "Metonymy and conceptual integration," the authors investigate the interaction of conceptual blending and metonymy. They demonstrate that Lakoff's and Kövecses' unidirectional model of conceptual metaphor does not account for expressions such as 'smoke is coming out of his ears', which can only be understood as resulting from "blending" the source and the target domains, since, literally, there are no ears in the source domain and there is no smoke in the target domain. Fauconnier and Turner's approach has far-reaching consequences for the theory of metaphor in that it may very well turn out that most metaphors involve conceptual integration. Also, conceptual entities may be metonymically linked in a blended space. In the well-known symbolic representation of death as 'The Grim Reaper', the input elements 'scythe,' 'cowl,' and 'skeleton' are conceptually integrated. Thus the blend "shortens" the metonymic distance between originally non-contiguous conceptual entities. (Klaus-Uwe Panther and Günter Radden)
